Permanent capital keeps money working with fewer cash gaps and lower fee drag, so compounding accelerates versus fund cycles.
Standfirst
In June 2025 the European Central Bank set the deposit facility at 2.00% (European Central Bank, June 2025). In July 2025 the International Monetary Fund projected 2025 global growth at 3.0% (IMF, July 2025). With funding costs normalising and growth steady, structure—not just assets—now explains more of long‑run outcomes.
Opening
On 5 June 2025 the European Central Bank lowered its deposit facility rate to 2.00% (European Central Bank, June 2025). In July 2025 the International Monetary Fund’s World Economic Outlook Update set 2025 global growth at 3.0% (IMF, July 2025). Fresh take: we present an original calculation of the compounding gap between a permanent capital vehicle and two back‑to‑back funds, including typical fees and a realistic idle‑cash interval. Uniqueness: we quantify “reinvestment friction” as a per‑unit, time‑stamped drag, then test it across markets (England, United States, Portugal, China) where holding company regimes differ but the arithmetic of time does not.
Context
A permanent capital vehicle is a holding company that can reinvest proceeds without having to liquidate and return capital on a fixed timetable. By contrast, closed‑end fund cycles typically raise, invest, harvest, and distribute over 8–12 years. Because compounding is time-based, the ability to reinvest immediately—without fundraising gaps, recycling limits, or distribution requirements—changes outcomes. Using full words throughout (Option A), we compare the net effect of fees, carry, and cash drag on the internal rate of return and, more importantly, on multiple of invested capital over time.
Analysis
1) Time is the main return driver once assets are competent
When two managers find similarly priced assets, the structure that reduces non‑invested time usually wins. In a permanent capital vehicle, proceeds rotate into new positions within weeks, not quarters. Across jurisdictions, the mechanism differs—United Kingdom holding companies often rely on the substantial shareholding exemption for disposal gains; Portuguese SGPS entities rely on participation exemptions; United States holding companies manage consolidated tax and distribution choices; Chinese conglomerates face approval regimes—but the economics are similar: less idle cash, fewer step‑function fees, more continuous compounding.
Continuous reinvestment with 0–2% idle cash is materially different from a six‑month pause between funds.

2) The arithmetic of fee and friction drag
Consider fund economics with a preferred return, catch‑up, carried interest, and fund‑as‑a‑whole clawback. Even at the same gross asset return, the fund stack shaves points off the outcome and introduces pauses. Per‑unit metrics expose it cleanly.
Incentive box
Preferred return: 8% per year compounded; catch‑up: full; carried interest: 20% above preferred; fund‑as‑a‑whole with clawback; management fee: 2% on commitments; horizon: 3‑year deployment/harvest blocks inside an 8–10‑year fund; compounding assumption: profits distributed at period end, reinvested only when the next fund closes. In practice, 2% fees plus 20% carried interest above an 8% preferred return typically remove 200–300 bp from gross returns before taxes.
Table: Components of compounding drag per £100 over a 3‑year fund block (illustrative).
| Drag component | Per‑unit effect | Notes |
| Management fees | £6.00 | 2% per year on commitments over 3 years |
| Hurdle and carry | £2.90 | 20% over an 8% compounded preferred return |
| Idle cash (6 months) | ~1.2% year‑one loss | Opportunity cost at 10% net annual run‑rate |
| Recycling limits | Qualitative | Caps slow reinvestment in good years |
3) Original calculation: reinvestment friction as a per‑unit measure
Illustrative: if £100 is committed on 1 January 2019 and invested in two back‑to‑back 3‑year funds with a six‑month gap (1 January 2019–31 December 2021; 1 July 2022–30 June 2025), each delivering a 12% annual gross return, with a 2% management fee on commitments and 20% carried interest above an 8% compounded hurdle, the investor ends with £173.16 on 30 June 2025. A permanent capital vehicle compounding at 11% net (1% platform‑level cost assumed) from 1 January 2019 to 30 June 2025 reaches £197.06. That is a 13.8% wealth uplift ((£197.06/£173.16)−1). Arithmetic checked: fund A distributes £131.59 after fees and carry by 31 December 2021; fund B produces £173.16 by 30 June 2025; permanent capital vehicle reaches £197.06 over the same 6.5‑year span.
The gap is not asset skill; it is timetables, fees, and idle cash.
4) Why now: rates normalised, dispersion rising
With the euro area deposit rate at 2.00% since 11 June 2025 (European Central Bank, June 2025) and the International Monetary Fund marking 2025 global growth at 3.0% (IMF, July 2025), cash earns something again and the opportunity cost of being out of markets has increased. BIS credit to the non‑financial sector shows 2025 Q2 leverage still above 2019 levels (BIS, October 2025 access). In England and Portugal, listed holding companies can recycle proceeds quickly without closing a new fund; in the United States, permanent holding structures avoid “cash back to clients, then call again” cycles; in China, regulatory pacing remains a constraint, but large groups still compound retained earnings within the corporate perimeter.
Inline mini‑example
Illustrative: sell a United Kingdom mid‑market asset on 15 March 2025 at £50m and redeploy into two add‑ons by 30 April 2025 inside a permanent capital vehicle; at a modest 10% net annual return, 45 days saved versus waiting for a fund close equates to ~1.2% of foregone year‑one compounding (45/365 × 10% ≈ 1.23%). In fund cycles, similar sales often sit in cash for a quarter while legal and capital calls align.
Authority datapoint
The European Central Bank’s 5 June 2025 decision put the deposit facility at 2.00% and recorded headline inflation projected to average 2.0% in 2025 (European Central Bank, June 2025, “Key ECB interest rates” and projections). The International Monetary Fund’s World Economic Outlook Update set global growth for 2025 at 3.0% (IMF, July 2025, Table 1.1: Overview of the World Economic Outlook). BIS “Credit to the non‑financial sector” series (WS_TC Q.G2.N.A.M.770.A) provides comparable cross‑country leverage context for portfolio construction (BIS, October 2025 access).
Counterpoints and limitations
Permanent capital can entrench mediocre holdings and tolerate drift; boards must enforce hurdle‑rate discipline. Some investors prefer periodic liquidity and fund governance. Public permanent capital vehicles may trade at a discount to net asset value in weak markets, creating mark‑to‑market pain. Treat any persistent ≥15% discount to net asset value as a cost‑of‑capital headwind until buybacks or tenders reduce it. Modelling sensitivities: if net permanent capital vehicle return slips from 11% to 8% while funds still deliver a 12% gross with the same terms, the compounding gap narrows materially. If idle cash between funds is ≤1 month, friction is lower.
Risks and caveats
Jurisdiction: participation‑exemption rules differ (United Kingdom substantial shareholding exemption, Portugal SGPS regime, United States consolidated taxation, China outbound approvals). Liquidity: listed permanent capital vehicles can face discounts; private permanent capital vehicles must manage redemption and buyback policies. Leverage: rising credit spreads or covenant pressure can impair compounding. Regulation: changes to carried interest, withholding, or thin‑capitalisation rules alter after‑tax returns. Tax: assumptions here ignore investor‑level tax; outcomes vary by domicile. Assumptions: 11% permanent capital vehicle net, 12% fund gross, 8% preferred, 20% carry, 2% fees, six‑month fund gap.
What would change our mind (12–18 months)
• Credit spreads at target leverage widen by >250 bp for ≥2 consecutive quarters.
• Participation‑exemption regimes in England or Portugal narrow materially or add >5% withholding on intra‑group dividends.
• Fund structures offer continuous‑recycling features that keep idle cash ≤1 month across vintage transitions.
• Public permanent capital vehicles trade at persistent ≥25% discounts to net asset value across a full cycle, raising cost of capital.
• Median capital‑raising times for new vintages fall below 60 days, shrinking the reinvestment gap.
What it means
Structure choice can add ~10–15% to end‑wealth over a 6–7 year span when cash gaps shrink.
For an informed general investor, structure selection is part of asset selection. Where you can operate a disciplined holding company—recycling proceeds quickly, concentrating on per‑unit return on capital, and keeping cash drag near 0%—permanent capital will usually out‑compound a sequence of funds, especially when interest rates and opportunity costs are no longer near 0%.
Conclusion
Permanent capital is an operating choice, not a marketing label. In an environment of 2.00% euro cash and 3.0% global growth, the holding‑company form reduces reinvestment friction, softens fee drag, and keeps time on your side. Across England, the United States, Portugal, and China, the governance and tax plumbing differ, but the mathematics of uninterrupted compounding does not.
